Implementation and validation of a strongly coupled numerical model of a fully passive flapping foil turbine

This paper presents the implementation and validation of a strongly coupled numerical model fully passive flapping foil turbine operating at high Reynolds number. Thanks to strong fluid–solid coupling strategy, well known added-mass instability is mitigated while simulating lightweight foil. The results are first validated in case fixed undergoing static stall. then with respect available literature for heavy turbine. Finally, compared experimental data prototype tested confined channel. have shown be good agreement measurements. Indeed, kinematics harvesting performances been accurately reproduced by simulations. Besides, leading edge vortex shedding observed experiments has also precisely results. implemented present constitutes useful tool expanding parameter space search an optimised design
